# Parse Server: session creation skips class permissions, sessions survive logout

Parse Server does not enforce the create and addField class-level permissions on the _Session class when sessions are created. An authenticated user, or anyone holding that user's session token, can create extra sessions for that user and add fields to _Session, and those sessions stay valid after the original session is logged out.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed Parse Server version with `npm ls parse-server` and compare it with `8.6.98` (8.x line) or `9.10.3-alpha.1` (9.x line).
- Review the Class-Level Permissions for `_Session` in your app to see whether create or addField is restricted.

## Fix

- Upgrade parse-server to `8.6.98` on the 8.x line, or to `9.10.3-alpha.1` or later on the 9.x line.
- After upgrading, log out and revoke any sessions that were created by untrusted users.

## From the sources

Parse Server before 8.6.98 and 9.0.0 before 9.10.3-alpha.1 does not enforce the create and addField class-level permissions of the _Session class when creating sessions. An authenticated user, or anyone holding that user's session token, can send POST requests to /sessions or /classes/_Session to create additional sessions for that user and add fields to _Session; these sessions are not revoked when the original session is logged out.
